#     powerpc: Wire up clone3 syscall
#     
#     Wire up the new clone3 syscall added in commit 7f192e3cd316 ("fork:
#     add clone3").
#     
#     This requires a ppc_clone3 wrapper, in order to save the non-volatile
#     GPRs before calling into the generic syscall code. Otherwise we hit
#     the BUG_ON in CHECK_FULL_REGS in copy_thread().
#     
#     Lightly tested using Christian's test code on a Power8 LE VM.
